The Brazil-based composer Alexandre Eisenberg wrote 'Arquichorinho' as a competition piece for the Brazilian National Flute Association (ABRAF). The music 'has been picked up on the streets of Rio de Janeiro' and takes up the temperament, rhythm and harmony of the traditional 'choro' which is probably the best-known musical form of Brazil. A rewarding concert piece ranging between folk and classical music and South American temperament on the concert stage!
